Post & Rail Buyers’ Guide
Post and Rail fencing is a classic, versatile solution widely used in both rural and urban environments to define spaces, provide safety, and enhance aesthetics. Its straightforward design, consisting of vertical posts connected by horizontal rails, makes it a practical choice for a variety of applications, from park boundaries and pedestrian pathways to commercial properties and public spaces.
This guide is designed to help you understand the technical aspects of Post and Rail fencing, enabling you to make informed decisions that match your specific requirements.
Post and Rail Fencing Materials
Cast Iron
Cast iron is a time-tested material known for its classic appearance and impressive strength. It offers excellent durability and can withstand heavy impact and harsh weather conditions. Cast iron’s natural brittleness is offset by its ability to be moulded into ornate and traditional designs, making it popular for heritage and high-end applications.
Ductile Iron
Ductile iron improves on cast iron’s limitations by adding flexibility and toughness. It is less brittle and more resistant to impact and stress, making it ideal for environments where structural resilience is critical. Like cast iron, ductile iron can be finished with corrosion-resistant coatings to extend its lifespan while maintaining a classic metal appearance.
Polyurethane
Polyurethane represents a modern alternative in post and rail fencing. It’s a durable synthetic material liked for its lightweight nature, excellent resistance to weather, UV rays, and chemicals. Polyurethane fencing requires minimal maintenance since it does not rust, crack, or warp. It can be moulded into a variety of textures and colours, allowing for versatile design options while providing long-lasting performance.
Key Features to Consider
Structural Strength and Load-Bearing Capacity
A post and rail fencing system needs to be able to withstand physical forces, especially in high-traffic areas. Materials like ductile iron and steel provide robust structural strength, capable of resisting heavy loads and harsh weather.
Corrosion Resistance and Weatherproofing
Post and rail fences are installed outdoors, where exposure to rain, sun, salt air, and pollution can also make deterioration faster. Materials such as stainless steel and polyurethane excel in resisting corrosion and weather-related wear. Protective coatings, like galvanisation or powder coating, also play a vital role in prolonging the railing’s life.
Maintenance Requirements
Different materials require varying levels of upkeep. Cast iron, while strong, needs periodic painting or treatment to prevent rust. Polyurethane and stainless steel require minimal maintenance, making them ideal for projects where long-term care needs to be minimised.
Aesthetic Options and Customisation
Beyond performance, the visual impact of post and rail fencing influences public perception and site integration. Materials like cast and ductile iron offer opportunities for intricate, traditional designs, while polyurethane and steel can be crafted into modern, sleek profiles. Colour, finish, and design flexibility allow you to tailor the fencing to complement the surrounding environment and street furniture.
Environmental Considerations and Sustainability
Sustainability is increasingly important in urban planning. Some materials, like steel and iron, are highly recyclable, which can reduce environmental impact. Polyurethane, while durable, is a synthetic material with different ecological considerations. Take a look at out sustainability page for more.
Installation and Maintenance
Proper installation and regular maintenance are crucial to maximising the lifespan and performance of your post and rail fencing system.
Installation Process
Installing post and rail fencing involves setting vertical posts securely in the ground, then attaching horizontal rails to connect the posts. The process typically includes:
- Site Preparation: Clearing and levelling the area where the fence will be installed.
- Post Placement: Digging holes for posts at specified intervals, which vary depending on material and design, typically between 2 to 3 meters apart.
- Anchoring: Posts are anchored in concrete or other solid foundations to ensure stability and resistance to environmental forces like wind or impact.
- Rail Attachment: Rails are fixed to the posts using bolts, brackets, or welding, depending on the material and design specifics.
Professional installation is recommended to ensure correct alignment, structural integrity, and compliance with local regulations or safety standards. At Broxap, our work is well co-ordinated throughout the project cycle. We offer a nationwide installation service that provides the full scope of works from civil requirements to steel work erection, cladding, electrical and finishing activities.
Foundation and Anchoring Options
The choice of foundation impacts the fence’s durability and performance. Common methods include:
- Root-fixed footings: Provide a solid, long-lasting base for posts, ideal for heavy materials like cast iron or steel.
- Surface mounting: Suitable for areas where digging isn’t possible; posts are bolted to existing concrete surfaces, though this method may be less stable in high-impact zones.
Longevity and Warranty
With proper installation and maintenance, post and rail fencing can last several decades. The expected lifespan varies by material:
- Cast and ductile iron: 25-50 years (with maintenance)
- Polyurethane: 20-30 years (low maintenance)
- Steel: 20-40 years (depending on coating quality)
- Stainless steel: 50+ years (minimal maintenance)
We offer a great range of warranties to protect your investment and provide peace of mind.
Choosing the Right Post and Rail System for Your Project
Match Materials to Environment and Usage Consider where the fence will be installed and how it will be used:
- Urban or High-Traffic Areas: Steel or ductile iron are excellent for locations needing strong, impact-resistant fencing.
- Coastal or Harsh Weather Zones: Stainless steel or polyurethane provide superior corrosion resistance against salt air, moisture, and UV exposure.
- Heritage or Decorative Projects: Cast iron offers a traditional, ornamental look, ideal for parks, historic sites, or high-end developments.

Post & Rail Fencing: FAQs
What
is Post and Rail fencing used for?
Post and rail fencing is commonly used to define boundaries, control pedestrian flow, and enhance safety in parks, public spaces, commercial properties, and rural areas. Its open design maintains visibility while clearly marking off areas.
What
materials are available for post and rail fencing?
Our systems are made from cast iron, ductile iron, polyurethane, steel, stainless steel, or a combination of these materials, each offering unique benefits depending on durability, aesthetics, and maintenance needs.
How
do I choose the right material for my project?
Consider factors like environmental conditions, maintenance capabilities, budget, and desired appearance. For example, stainless steel is ideal for coastal areas due to its corrosion resistance, while polyurethane requires minimal upkeep for urban settings.
Is post
and rail fencing difficult to install?
Installation complexity depends on material, site conditions, and foundation type. Typically, posts are anchored securely in the ground and rails attached using brackets or welding. Professional installation is always recommended to ensure safety and durability.
How
long does post and rail fencing last?
Lifespan varies by material: cast and ductile iron can last 25-50 years with proper maintenance, polyurethane around 20-30 years with low maintenance, steel 20-40 years with protective coatings, and stainless steel 50+ years with minimal care.
